Clausen and Tate are gone. Sorry, folks--it's not like Leinart sticking around--he knew they'd have a shot at the title (his 3rd in a row) and he knew he wouldn't get sacked if he came back. He probably also knew that the chance of being immortalized as the most successful QB in college history (he finished 37-2, with one loss coming when his D couldn't tackle Vince Young) was too good to pass up. And, he probably wasn't all that excited in the NFL-his heart wasn't (and isn't, apparently) in it
Take one look at Clausen, ripping his chin-strap off with disgust 20 times a game--he believes he's too good for ND and college football itself. If Weis gets fired like you all breathlessly demand, he'll have no reason to stay. He's not going to better his draft position by sticking around. The talent pool of NCAA QBs is startlingly thin which is why he's even been mentioned as a Heisman favorite. Brady Quinn was a far better college QB than Clausen and he certainly had a better attitude. As a Trojan, even I respected his game. He took some brutal physical beatings from Lawrence Jackson & Co. but he still stood in there and threw some great balls. And he didn't trudge around with a sour look on his face all the time and act like his teammates were idiots. In time he will prove to be a far better pro than Clausen.
Tate is a serious prospect and based on his showboating and taunting in the SC game, he is already mentally in the NFL. There's just no way he and Jimmy sit down and say "let's come back and try to win it all." They know that #5 isn't enough to make that crappy "D" sufficiently adept to win more than 10 games next year.
Sorry, folks, as college football fans we'd all love to see these guys stay all four years, but the money's too good and the risk is too high. Sanchez, despite some of his heroics this year, as Carroll said probably shouldhave come back, given he'd only had 13 starts, but then again, given the fact last year's draft was thin and he went 5th, had he come back this year and won it all I'm not sure he would have gone any higher. Financially, he made the right call. But he'll always wonder if he could've hoisted that crystal football!
